3sgte swap, ECU Question Options

[115celi]

Basically, I am middle of a 2nd gen 3sgte swap and my wiring is setup for a 90-91 ecu (pinout from DR Tweak). It cranks but there is no spark. We have checked the igniter, coil, distributor and wires using the BGB from celicatech, and they all check out.

I went to google to see if I could find any info and ran across a web-site with some ecu part numbers. http://www.toysport.com/webpages/WebUpdate...A20ECU20WEB.htm
I found an ecu that had 89661-20760 for the part number and was wondering if there is a difference between this one and the 89661-20750?

I thought mine was right, I thought the part number on the ecu was 89661-20750 but part of the 5 is missing and it isn't really legible. I figured it was right based on the part numbers listed in a thread I found.
JDM 185 ecu's-
89661-20750=89/10-90/03(superceded to 20751)
89661-20751=90/03-91/08
89661-2b310=91/08-92/02
89661-2b280=91/08-93/09

Does anyone know if there is any difference between the ecus with 89661-20760 and 89661-20750, thanks.

Now I am really confused. I did a trouble shoot to figure out why I was getting those codes and all of the sensors are good, the wiring checks out and the ecu should be good(unless I have two bad ecus, becaues they both pop the same codes).
I am out of ideas. Even with those codes the enigne should try to turn over wouldn't it? Is there anything else I should check to get ride of the codes?
